The United Nations (UN) deals with many problems when trying to solve conflicts and keep peace around the world. Here are some of the main challenges they face:

1. Money Problems:

   • For 2021, the UN planned a budget of about $6.37 billion for peacekeeping.
   • However, they often don't get enough money on time, with only about 70% of the needed funds coming in as expected.

2. Political Issues:

   • The five permanent members of the Security Council (the U.S., U.K., France, Russia, and China) can say “no” to UN resolutions.
   • This has happened over 250 times since 1946.

3. Complex Operations:

   • Right now, more than 80 million people around the world are displaced from their homes.
   • This makes it much harder for the UN to help during times of conflict.

4. Mandate Limitations:

   • Many peacekeeping missions have rules that don’t cover everything that needs to be done to resolve conflicts.
   • This limits what they can accomplish.

5. Local Resistance:

   • For the UN to work well, they need the support of the countries they are helping.
   • If the local government doesn’t cooperate, it can really hamper their efforts.

These challenges greatly affect the UN's ability to keep peace and security around the world.
